[BluffTHIS!]

I presume you mean views which are unknowingly incorrect rather than maintaining the truth of a known falsehood for some psychological or manipulative reason. The only advantage that could accrue from an incorrect view is one which would lead one to pursue an action that had a beneficial result but which action would not have been taken were the truth known. The only such advantage I personally have experienced is misreading an opponent's hand on an early street and calling an allin bet with insufficient pot odds but sucking out on the river.
